A review and comparison of each model

Energy star rated for efficiency

1. Honeywell TP30KWN 30 pint

Honeywell is one of the biggest brands in dehumidifiers so it was natural to choose the Honeywell TP30WKN dehumidifier as one of the best 30 pint dehumidifier models on the market!

It is energy star qualified which is great for you because you will save energy and money on lower power bills.

It has a washable air filter which prevents white dust from being dispersed, something that many other dehumidifiers have problems with. And there’s no need to replace the filter- simply hand wash it and then put it back inside the dehumidifier.

You will know when to clean the filter because there’s a filter clean alert on the dehumidifier.

The water tank is detachable making it easy for you to empty it when it is full. It holds up to 30 pints per day before needing to be emptied.

If you prefer the automatic method, there is a drain hose included with the dehumidifier so that it empties the water for you using gravity.

The dehumidifier is also portable and can be easily moved from one room to the next.

There’s a sleep mode if you need to use the dehumidifier while you’re sleeping, so you won’t be disturbed.

The Honeywell 30 pint dehumidifier has a 24 hour on/off timer which will save you energy and money and there’s an auto restart function in case of a power surge. This saves you worrying about switching it back on if there is a power surge- it will automatically happen.

Honeywell is a name you can trust when it comes to buying a dehumidifier for your home and when choosing the best bathroom dehumidifier, you won’t go wrong with Honeywell.

Our runner-up pick

2. Inofia 30 pint

The Inofia 30 pint dehumidifier is an energy efficient dehumidifier suitable for use in your humid bathroom.

It’s built-in humidistat lets you select your desired humidity % and the dehumidifier keeps track of the humidity in the room and switches on an off depending on the desired level. You won’t need to buy a separate digital hygrometer and you’ll save money on your power bills because the dehumidifier only works when it needs to.

The auto shutoff and auto restart functions switch the power on and off according to the humidity level you want in your bathroom. You don’t need to worry about measuring the humidity yourself and switching the dehumidifier on and off!

The 24 hour on/off timer is also handy so that you don’t need to remember to turn it on or off and this will also save you money on your energy bills because you won’t be running it unnecessarily. Save even more power by adjusting the fan speed too.

You can empty the 0.5 gallon tank when it is full either manually yourself or attaching the 6.56 foot drain hose to the dehumidifier and letting it drain using gravity.

If you live somewhere cold, your bathroom can get cold while still being humid and luckily the Inofa 30 pint dehumidifier has an auto defrost function which allows it to be used in a cold climate without freezing up like other appliances would.

The Inofia 30 pint dehumidifier’s recessed handle and compact size makes it easy to move the dehumidifier in and out of your bathroom, especially if you plan to use it in other rooms in your home. It also makes it easier to empty the tank manually if you’re not going to use the drain hose.


Energy efficient saving you money on energy bills

Auto stop and auto restart so you don’t need to keep stopping and starting it yourself

Auto defrost so it can be safely used in cold temperatures

Power outtage restart so you don’t need to worry if there’s been a power outtage

3. Airplus 30 pint

The Airplus 30 pint dehumidifier is a great dehumidifier for bathroom use.

Its water tank holds 1.5 liters of water. Once it’s full, you can either manually empty the water or you can use the included drainage hose for continuous draining.

We love the Airplus 30 pint dehumidifier because of the 4 different modes available: standard mode, drying mode (for clothes drying), sleep mode (reduces noise if using at night) and raining mode (more powerful for wet, humid conditions). It’s a great dehumidifier to use in your bathroom or laundry when air drying your clothes.

The Airplus 30 pint dehumidifier’s washable reusable filter prevents white dust in the room after using the dehumidifier which tends to happen with other non-filter models. You can just wash and reuse which means you won’t need to buy replacement filters.

It’s easy to move the Airplus dehumidifier around because it has universal wheels making it portable and easy to use throughout your home.

It comes with a 2 year warranty for peace of mind!

Best budget option

The Pro Breeze Mini Dehumidifier is a popular option for those wanting a small but efficient dehumidifier for a small room or space such as a bathroom, small laundry or baby nursery.

The Pro Breeze dehumidifier uses Peltier technology, meaning that it can extract more moisture than other dehumidifiers while still using the same amount of power. The technology improves its efficiency.

The water tank can hold up to 16 ounces of water. The unit extracts up to 8 ounces per day.

Operation is 23 watts.

The Ivation IVADM35 dehumidifier is an excellent choice for bathrooms and other small rooms, and especially recommended for use in areas with high levels of humidity.

It’s a great mini dehumidifier for bathroom use especially if you have a small bathroom or want to use it in an ensuite.

The unit uses both Peltier and ERS technologies. ERS technologies help to balance the temperature of the Peltier element, which is typically hot on one end and cold on the other. By balancing the temperature, the unit is able to extract more moisture using the same power consumption as a unit without the ERS technologies.

It can extract up to 12 ounces of moisture per day, and the water tank has a capacity of 22 ounces. This is greater than most other dehumidifiers currently on the market.

Once the water tank is full, the LED indicator light changes from blue to yellow which indicates it needs to be emptied. When the water tank is full, the unit shuts off automatically.


ERS technologies allows more extraction of moisture

Larger tank capacity

Ideal for those living in very humid climates


Doesn’t have a large capacity

Not as good for very humid or large bathrooms

bathroom dehumidifier review

A quick summary of what to look for when choosing the right model

  • Will the dehumidifier be used in the bathroom only or laundry or other room too? Make sure the size you choose suits all rooms the dehumidifier will be used in. Castor wheels make it easy to move. Choose a portable dehumidifier for bathroom and other room use.
  • How often do you want to empty the water tank? Look at the amount of water that can be removed in one day and the water tank capacity to work out how often you would need to empty the tank. Of course, also consider how many hours per day the dehumidifier will be used for
  • How big is your bathroom? Choose the right size dehumidifier for your bathroom. A small bathroom or ensuite may only need a mini dehumidifer

Electric dehumidifiers can be used in many rooms and areas around your home. They are used in a bathroom, basement or a crawl space where humidity is an issue. If your bathroom doesn’t have a fan, then a small sized dehumidifier for bathroom use is a perfect way to remove moisture. You can also find bathroom dehumidifiers that are wall mounted and ceiling mounted.

A small bathroom dehumidifier is either compressor-based or uses Peltier technology. Peltier technology is better because it’s more energy efficient, there is less noise and the dehumidifier is lightweight.

It’s important to know that dehumidifiers remove the moisture in the air, but they cannot cool down the air like an air conditioner can.

Not all dehumidifiers are the same. When choosing the best dehumidifier for bathroom use, there are some differences you will need to be aware of between each of the units.

Differences to look out for are the technologies used, the moisture extraction ability and the water tank capacity. The larger the tank capacity, the less often you will need to empty the water. This is particularly important for those who live in very humid climates.

How to compare each model?

How do each of the bathroom dehumidifier models we’ve reviewed compare to each other?

Each dehumidifier has a water tank capacity, which is how much moisture the unit can hold. Each model also has a maximum capacity that can be withdrawn from the air per day. The key is to find out how often you would need to empty the water tank.

Looking at the mini bathroom dehumidifiers, if they were running all day every day, you would need to empty the tank about 1.5 days after use. However the reality is that the dehumidifier wouldn’t run all day in a bathroom. But if this is something you find important, then choose the Ivation as it withdraws a lot more moisture per day than the other models reviewed and has a larger water tank capacity.

If you’re thinking of using your bathroom dehumidifier in a laundry too, we recommend choosing one of the larger bathroom dehumidifiers. This is because a laundry, especially if you’re drying clothes in one, would be more humid and for longer periods than a bathroom where people typically have a shower or bath (and hopefully not for hours!).

We recommend the Honeywell 30 pint dehumidifier or the Inofia 30 pint dehumidifier. As they are both on castor wheels, they would be easy to move from a bathroom to your laundry.

Can I use it in the bathroom?

Yes, by using a dehumidifier in your bathroom you are helping to prevent problems with moisture, mold and bacteria growing. This is because the dehumidifier will remove the moisture in the bathroom. Moisture is what is need for mold and bacteria to grow.

Now that you know that dehumidifiers do work in bathrooms, it’s time to choose one to buy. Read our bathroom dehumidifier reviews to find the best brand and model dehumidifier for your bathroom.

What size do I need?

Your best option is a 30 pint dehumidifier which is perfect for a bathroom but can also be used in other rooms in your home. You can read more about dehumidifier standards as set out by the U.S. Department of Energy.

Small dehumidifiers for bathrooms that extract up to 8 ounces of moisture per day are suitable for your bathroom. These dehumidifiers have water tanks that typically hold up to 16 ounces of water.

A common error many people make is buying the wrong type of dehumidifier, one that is too small or not powerful enough for the room they need to dehumidify. The best dehumidifier for bathrooms won’t be suitable for a large basement. And a large dehumidifier better suited to a basement may be too noisy and large to be placed in a bathroom.

The dehumidifiers we have reviewed in this post are all suitable sizes for a bathroom. They are smaller than your average dehumidifier unit.

Different types of technology

Small dehumidifiers for bathrooms typically use a compressor or Peltier technology. Peltier technology is used to control the temperature- the Peltier heat pump cools the surface and condenses the water vapor from the humid air. Peltier technology means no moving parts are required, and operation is much quieter when compared with a dehumidifier that uses a compressor. It also makes the unit lightweight.

Efficiency levels

When deciding on a dehumidifier for your bathroom, it’s a good idea to know how much moisture the unit can extract before the water tank needs to be emptied. It’s also important to know how much power the unit consumes. By knowing these two pieces of information, you can determine whether the dehumidifier is efficient. If you can find a unit that extracts a larger amount of moisture but at the same power consumption level of a dehumidifier with a lower extraction, then you know you have found an efficient dehumidifier. This is important for the environment, and for your wallet!

Water tank capacity

If your bathroom dehumidifier has a large water tank, then it means you will not have to empty the tank as often as a bathroom dehumidifier with a smaller tank. This is because the water tank can hold more moisture. If you live in a humid climate, then it’s recommended you find a bathroom dehumidifier that has a larger tank capacity.

Common complaints

The most common complaint that people make about dehumidifiers is that they are not working properly, simply because there isn’t much water in the water tank. Sometimes there may be a fault with the unit itself, but usually the problem is that the room is not very humid to begin with. Humidity levels in a room and the relative humidity level are important to measure before deciding if you need a humidifier or a dehumidifier.

Another problem could be that the wrong type of dehumidifier has been purchased for that particular room or space. As mentioned earlier, a small dehumidifier for bathroom use won’t be suitable for a large basement.

Another typical complaint about dehumidifiers is the noise level. Just like any other appliance, a dehumidifier will make noise. Whether the noise is loud or not is subjective, but it is often described as sounding similar to an air conditioner. Keep this in mind when purchasing a dehumidifier- expect some level of noise.

One final word…

These are our top picks of the best dehumidifiers for bathrooms, and our reviews of each dehumidifier. Your choice will largely depend on your budget, your bathroom’s humidity level and your personal preference.

Once you start using your new dehumidifier, you will notice a difference to the level of humidity in the bathroom. It will improve the air quality (much like an air purifier can) and reduce mold, bacteria and germs that breed in humid rooms.
